UNITED STATES JOHN DEMAREST, OF NEW YORK, N. Y., ASSIGNOR TO THE J. L. MOTT IRON VORKS, OF SAME PLACE.

CISTERN FOR WATER-CLOSETS.-

SPECIFICATION forming part of Letters Patent No. 298,452, dated May 13, 1884.

Application filed April 4, 1884. (No model.)

To aZZ whom it may concern:

Be it known that I, JOHN DEMAREST, of

the city and State of New York, have invented an Improvement in Cisterns for Water- Olosets, of which the following is a specification.

This improvement is for the purpose of lessening the expense in constructing the cistern, and for rendering the same very simple and durable.

In the drawings, Figure l is a plan view of the said cistern, and Fig. 2 is a cross-section of the same.

The cistern is a cast-iron box with sides a, ends b, and bottom 0, and below the same is the servicebox d, cast with flanges 6, through which screws are passed to fasten the box tightly to the cistern. A suitable packingsuch as red 1eadis introduced between the surfaces, to make the box water-tight. The pipe f, leading to the closet, is attached to the servicebox by the tubular screw-coupling g. These parts are of usual character. So, also, are the supply-valve K and ball-float L. There is an opening through the cistern-bottom 0 into the service-box d, and within this is secured the brass valve-seat m, having a dishing upper surface for the ring-valve n around the tube 1). This tube p has a flange above and below the rubber ring-valve n, to keep it in place. The lower end of the tube p is a guide for the Valve, and it slides in the seat m, and it is slotted to form passage-ways for the water when the valve is raised.

At the upper end of the tube p there is a cap, q, and there are openings at 1', through one side, and one end of this lever extends over the end of the cistern for the wire or pullchain. The other end of this lever extends out over the top of the cap q, and it is perforated for the reception of the screw u, that passes loosely through such lever and screws into the cap q. The weight of this lever presses upon the upper end of the cap q, and tends to 7 the cap q, the lever s, and the screw passing through a hole in the lever into the said cap q, substantially as set forth.

2. The lever s, pivoted at the inside of the closet-cistern and extending out aterally, in combination with the tube 10, the cap at the upper end of such tube, the screw passing through the lever into the cap, the washer Z, the valve it around the tube p, and the brass valve-seat secured in the bottom of the cistern, substantially as set forth. Y

Signed by me this 28th day of March, A. D. 1884.
